唑类缓蚀剂在电路板生产上的应用

The Use of Azoles in PCB Fabrication

鉴于电路板生产过程中环保和成本的要求，采用唑类缓蚀剂取代传统的锡铅合金镀层以保证可焊性。探讨了唑类缓蚀剂的保护机理、应用情况及发展前景。

In view of the improvement on environmental protection and the reduction of costs for PCBfabrication, emphasis has been placed on the use of corrosion inhibitors as replacements for conventional tin -lead electrodeposits for the preservation of solderability. The protection mechanism of azolesas well its their application rsults and challenge in future was investigated.
